Is it the weather or a dirty house that brings cockroaches inside?

Cockroaches can live happily in extreme heat and extreme cold so weather is not a factor in attracting them into your home. But a dirty home is something a cockroach will be attracted to. The female Germanica Cockroach, which is the most common pest in homes carries its egg capsule or ootheca, containing about 16 eggs under its abdomen, until the eggs are about to hatch. Then it is searching for a nice place to start its new family where there is plenty of food about. It will be particularly attracted to stored food products such as larders in any home. But also people who leave bits of food around everywhere and do not bother to sweep up, that will be just what the mother cockroach is looking for. Because she will deposit her egg capsule in a safe spot where there is food nearby. Her egg capsule is likely to be deposited in a dark damp nook or under floorboards in such dirty homes. So if you do not bother to clean up under the table after eating or leave bits of food all over the carpet and kitchen floor or leave bits of food on floor in your bedroom, a female cockroach ready to deposit her eggs for hatching will find your home a perfect place to start her new family. Thereafter cockroaches will happily breed and multiply in that location. So the dirtier and more unhygienic you are, the more attractive will your home be to cockroaches to also live there. But it would be wrong to assume that people who are extremely clean and tidy will not necessarily have cockroaches breeding in their home too, particularly if previously established there.
